WINDOW.

Specification of Letters Patent.

Patented Aug. 7, 1906.

To all whom, it 7er/ay concern,.-

Beit known that I, GEORGE W. BUFFING- TON, a citizen of the United States, residing at Mechanicsburg, in the county of Champaign and State of Ohio, have invented certain. new and useful Improvements in Windows, of which the following `is a speciiication, reference being had therein to the acf companying drawings.

This invention relates to windows, and has for its obj ect to provide a construction Whereby the usual sash-weights for counterbalancing the sashes may be dispensed with and whereby, the proportion of the area of the window-opening available for ventilation or other purposes may be increased over that usually available where two sliding sashes are employed.

To these and other ends my invention consists in certain novel features, which I will now` proceed to describe, and will then particularly point out in the claims.

In the accompanying drawings, Figure 1 is an outside elevation of a window embodying my invention in one form. Fig. 2 is a vertical sectional view of the same, taken on the line x of Fig. 1 and looking in the direction of the arrows. Fig. 8 is an enlarged detail sectional view taken vertically through the casing of one of the sets of pulleys for the sash-cords. Fig. 4 is a detail sectional view taken on the line y y of Fig. 1 and looking in thedirection of the arrows, and Fig. 5 is an enlarged detail view illustrating the catch or fastening by means of which the sashes are locked together when the window is closed.

In the said drawings I have shown a suitable window-casing comprising the jambs 1, lintel 2, and sill 3. The jambs are provided with two parallel stops, a front stop 4 and a rear stop 5, forming two continuous grooves or guideways 6, one on each side of the frame, in which grooves or guideways both sashes slide, moving in the same plane instead of in parallel planes, as in the case of the usual sliding double sashes. The upper sash is designated by the reference-numeral 7 and the .lower sash by the reference-numeral 8.

. l. Said sashes are preferably of equal size, each sash4 having a height equal to one-third ofthe height of the window-opening, measured, from the sill to the lintel. The sashes are. connected to move in unison by a cord orrope 9 at each side, only a single cord be ing employed at each side, and said cord having its extremities respectively attached to the upper and lower sash. The interme-A diate portion of each cord passes over a supporting-pulley 10 and guide-pulley 11, said pulleys forming a pair, being mounted close together and one below the other in a housing 1,2, secured in a recess in the jamb 1. Each cord has one of its ends secured to one side of the upper sash 7 near the lower portion thereof, as indicated at 13, and said cord extends upward in a groove 14 in the stile 15 of said sash. It then passes around or over the supporting-pulley 10, which is arranged to project into the guideway 6 between the stops 4 and 5 to an-extent sufficient to bring the portion of the cord 9 which depends directly therefrom and which is connected to the upper sash 7 into proper position to cause it to lie within the groove 14. The cord 9 after passing over the supporting-pulley 10 is deflected outward by the deilectingpulley 11, so that the portion thereof which extends downward from said deflecting-pulley lies in a groove 16 in the face of the jamb 1, down which groove it extends, and is connected at its extremity to the lower sash 8 at 17. The stile of the lower sash may also be grooved, if desired, to accommodate the cord 9, and it will be understood that the groove 14 in the stile of the upper sash is of dimension such as to permit it to pass the projecting` portion of the supporting-pulley 10'. It will further be understood that the construction just described is duplicated on each side of the window. u

Below the sill-3 the window-frame is provided with a pocket 18, into which the lower sash 8 may slide. The upper third of thek window-opening below the lintel 2 is closed in front of the front stop 4 by means of a ixed sashv 19, back of which the upper sash may slide. In the position of the parts shown in the drawings the window is closed, and it will be seen that the entire window-opening from the sill to the lintel is glazed or closed by glazed sashes, so that the entire windowopening is available for the admission of light. The window may be opened either by pushing down the lower sash or pushing up the upper sash, as may be most convenient, the two sashes moving in opposite directions in either case, the lower sash moving down IOO the upper sash moving into the space back of the xed sash 19. When the window has thus been opened, it will be seen that two thirds of the space between the sill and lintel is unobstructed and available for venti lation or other purposes, whereas with the ordinary sliding double sash only one-half of the space is thus available. It will also be seen that the usual sash-weights and the necessary casing-spaces therefor are entirely done away with and that only a single cord is required at each side of the window instead of two cords at each side, as in the usual construction.

It will be noted that the lower rail 2O of the sash 19 extends inwardly between the front stops 4 to a meeting with the top rail 21 of the upper sash 8 to close the window at this point, such extension being indicated by the reference-numeral 22 and forming what is known as a check7 for the purpose indicated. Similarly the sill 3 extends rearwardly between the stops 4 to a meeting with the lower rail 23 of the lower sash 8 for the same purpose. In order to form a tight joint between the meeting-rails of the sashes 7 and 8, one of said rails-for instance, the top rail 24 of the lower sash S-is provided with a rib 25, and the bottom rail 26 of the upper sash 7 is provided with a corresponding groove 27.

The sashes may be secured together in any suitable manner, the construction which I prefer for that purpose being that shown enlarged in Fig. 5 of the drawings. In this construction the bottom rail 26 of the top sash has pivotallyl connected thereto a gravitylatch 28, the lower end of which is provided with a beveled face 29 and a hook 30, the latter adapted to engage under the top rail 24 of the lower sash. Saidtop rail is provided with a metallic guard-plate 31, having a top iiange 32, against which the beveled end surface 29 of the latch strikes as the sashes approach each other, thus causing the latch to swing outward, and a bottom flange 33, against which the hook 30 engages when the sashes meet. The latch may be provided with a knob or handle 34, by means of which it may be readily operated to disconnect the sashes.

Although I have described the fixed sash A 19 at the top of the window-opening as a glazed sash, it is obvious that said sash need not necessarily be of that character, since a panel may be employed at that point, if desired, in which case the upper sash may be regarded as sliding into a pocket at the top of the window just as the lower sash slides into a pocket at the bottom of the window. In view of this and other obvious modifications I do not wish to be understood as limiting myself strictly to the precise details of construction hereinbefore described and shown in the accompanying drawings.

The housing 12 1s provided with an inwardly-extending guiding portion 12a, so located that when the cord is being inserted in position in the housing and relatively to the pulleys its forward end after passing over the upper pulley 10 will be deflected outward and guided between the pulleys l0 and 11, so that its end will project in position to be grasped, thus allowing the cord to be readily inserted in position without the use of any special devices for assisting in the operation.

Having thus fully described my invention,

what I claim as new, and desire to secure byV Letters Patent, is-

1. In a window, a frame having a guidewayin each jamb thereof, and a pocket alined with said guideways and extending below the sill, in combination with two sashes sliding in the same plane in said guideways, a single cord connecting said sashes at each side of the window, and a pair ofpulleys mounted close together and constituting sup orting and guiding pulleys for each of sai cords, each of which runs over one of the pair and against the other whereby the sashes are caused to' move simultaneously in opposite directions and counterbalance each other,

substantially as described.

2. In a window, a frame having a guidewayin each jamb thereof, and a pocket alined with said guideways and extending below'the sill, the upper third of the window-opening below the lintel being closed in front of said guideways, in combination with two sashes sliding in the same plane in said guideways and adapted to close the lower two-thirds of the window-opening, a single cord connecting said sashes at each side of the window, and a pair of pulleys mounted close together and constituting supporting and guiding pulleys for each of said cords, each of which runs over one of the pair and against the other whereby the sashes are adapted to move simultaneously in opposite directions and counterbalance each other, the lower sash lying in the pocket below the sill and the upper sash in the closed space below the lintel when' the window is open, substantially asdescribed.

3. In a window, aframe having a guide-A Way in each jamb thereof, a ocket alined with said guideways and exten ing below the sill, and a iixed'sash closing the upper third of the window-opening below the lintel in front of said guideways, in combination with two sashes sliding in the same plane in said guideways, a single cord connecting said sashes at each side of the window, and al pair of pulleys mounted close together and constituting supporting and guiding pulleys for each of said cords, each of which runs over one of the pair and against the other whereby the sashes are adapted to move simultaneE ously in opposite directions and counterbalance each other, the lower sash lying in the pocket below the sill and the upper sash lying IOO IIO

IIS

back of the fixed sash when the window is open, substantially as described.

4. In a window of the character described, a frame having Jfront and rear stops Jforming a guideway in each jamb thereof, and sashes sliding in the same plane in said guideways, in combination with a supporting-pulley eX- tending into each guideway and a deflectingpulley below each supporting-pulley, the upper sash having its stlles vertlcally grooved, and the jambs being vertically grooved below the delecting-pulleys, and a single cord on each side of the window, having its ends respectively connected to the upper and lower sash, its intermediate portion passing over the supporting-pulley and being guided by the delecting-pulley, and its depending portions lying respectively in the groove of the upper sash-stile and the groove of the jarnb, substantially as described.

. In testimony whereof I aflix my signature in presence of two witnesses.
